WILLCOX MSW LANDFILLL - Municipal Solid Waste Landfill in Willcox, Arizona

WILLCOX MSW LANDFILLL is a municipal solid waste landfill located 0.5 miles north of I-10 on Fort Grant Road in Willcox, Arizona, within Cochise County. The facility is currently operational and handles solid waste disposal for the surrounding community. As a landfill, it plays a key role in the region's waste management infrastructure. The facility operates under the regulatory framework of the US EPA, including RCRA Subtitle D for municipal solid waste landfills and Clean Air Act regulations for landfill gas emissions. In Arizona, landfills must comply with state-specific requirements for liners, leachate management, and groundwater monitoring. The NAICS code 562212 indicates this is a solid waste landfill facility. Environmental considerations for this landfill include methane gas generation from decomposing waste, which requires collection and control systems to reduce greenhouse gas emissions. Leachate management is also critical to prevent groundwater contamination, especially given the arid climate of southeastern Arizona. The facility's proximity to I-10 and the community of Willcox necessitates careful traffic management and odor control.

The Willcox area is in a semi-arid region with low annual rainfall, which reduces but does not eliminate the risk of leachate generation. Groundwater resources in the region are vital for agriculture and local communities, making leachate containment and monitoring essential. Landfill gas, primarily methane, must be collected to mitigate greenhouse gas emissions and potential explosion hazards. The facility's location near a major highway also requires dust and litter control measures.
